移动知识管理的情境感知体系结构研究

A Study on Context-Aware Architecture for Mobile Knowledge Management

文章提出移动知识管理的情境感知体系结构,分为四个层次:第一层是移动用户或移动代理;第二层是支持JAVA的移动设备;第三层是Contextualizer——智能中间件作为相邻层的连接纽带,它是该体系的核心层,根据用户依赖、技术环境、环境和任务等四种情境要素来解析查询和分析情境;第四层是由不同数据库类型的知识资源组成。四个层次中设备及代理之间交互传递使用户能够通过手持设备与数据库中心进行知识的创造、获取、联系、组织和检索等活动,在任何时间、任何地点都能够得到有效的知识支持。

The paper proposes an architecture for mobile knowledge management, which is divided into four layers. The first layer contains the mobile users or mobile agents. The second layer consists of Java-enabled mobile devices. The third layer is Contextualizer, which implements middleware serves as the connecting link between the adjoining layers and is the core players of the architecture, it parses the request and analyzes the context according to the following four context elements： user dependency, technological environment, situation, and task. The fourth layer contains the knowledge source which is built up of different database types. The interaction of the equipment and agency of the four layers makes user access the database center for knowledge creation, acquiring, contact, retrieving and other activities by mobile devices, at anytime, anywhere, attains effective knowledge support.
